Welcome to Radio Active, a Sunday evening report from POP! Goes The Charts that gets to the chart of the matter: all the highlights from the CHR/Top 40 chart, as published by Mediabase 24/7 and Mediabase Research. Happy New Year and welcome back! Lots of action on the airwaves this week, as programmers wake up from the bitterly cold break with plenty of presents to keep us warm. The first Radio Active report of 2018 starts much how the last report of 2017 began:

SEVEN WONDERS: Surviving through the slow holiday season and into 2018, Camila Cabello‘s biggest solo release to date, the Young Thug-assisted “Havana”, grabs a seventh week on top of the CHR/Top 40 chart. The global hit, taken from her forthcoming album Camila, is the longest-running #1 song at the format since Ed Sheeran‘s “Shape Of You”, which spent a total of ten weeks at the summit last spring. Her follow-up single, “Never Be The Same”, climbs from 34-30 this week, as it officially impacts on Tuesday. (Much of the panel is already on it, with adds spread out over the last few weeks, so don’t expect a big result.) “Havana” is still about 900 spins away from its nearest competitor, and with her aforementioned set due on Friday, there’s still a small chance that it could lead the chart for an eighth week. We’ll see! Regardless of what happens, she’s still a winner.

FILTHY AND FINESSE-Y: Two of this week’s top 40 entries were released at the end of last week to massive sales and streaming debuts, as well as hourly airplay on their respective first days in the market. The latter one, “Filthy” by Justin Timberlake, was all over the place on Friday and bursts into the countdown this week all the way up at #22, marking his 29th solo entry since 2002. His return to the pop format comes a week shy of the 20th anniversary of the impact date for what would become *NSYNC‘s debut U.S. hit, “I Want You Back”, which eventually went to #5 that May. In with a still-impressive 19th top 40 song is hitmaker Bruno Mars, whose remix of “Finesse” (along with Cardi B, now in with her second top 40 hit) launches at #33. The new jack swing release is an updated version of an album cut from his 2016 set, 24K Magic, which you’ll be hearing plenty about with the Grammy Awards a few weeks away. Further down the chart, the song “Home” (#39) by Machine Gun Kelly (third top 40 hit), X Ambassadors (fourth) and Bebe Rexha (12th) boosts the soundtrack to the Netflix movie Bright, while Post Malone‘s “I Fall Apart” (#40) lands the 22-year-old performer his fourth top 40 single (third from Stoney) at the format since 2015.

PUMP UP THE VOLUME: In addition to all the excitement in the top 40, another three songs are new to the top 50 this week. At #48, we find a big Urban (#10) and Rhythmic (#11) hit from chart newcomer Lil Pump, who enters with “Gucci Gang”. The rapper, 17-year-old Gazzy Garcia, released his self-titled debut last year, reaching #3 on the Billboard 200 list. Two additional EDM releases come in just below that single, with “First Love” (#49) bringing together the duo Lost Kings and two-time top 40 entrant Sabrina Carpenter, with “All Falls Down” (#50) linking Alan Walker with another singer with two top 40 tracks, Noah Cyrus, as well as Digital Farm Animals, who appeared (in a featured role) on Louis Tomlinson‘s “Back To You” (#24) in 2017. Will the two guys of Lost Kings or Walker, who have achieved plenty of top 40 hits to date on the Dance survey, finally manage their first top 40 hit on the CHR chart? We’ll see soon!
